The Cricket is a low cost entry level minimalist CW transceiver for the 20 meter band.  The 40M version was chosen as the build session kit for OzarkCon 2019, it bears a family resemblance to the well known but much lower performing Pixie.  However, this is NOT a Pixie, it is very different, vastly improved, and far superior the Pixie.

It features low parts count, better components including MOSFETs for better sensitivity and switching, and a modern NJM2113D audio amp.

A TX/RX offset is also included so that you can work other stations that have zero beat you, or are using a crystal on the same frequency.  Full QSK and a sidetone complete the essential operating features.  David's famous etched spiral coils are included on the pc board, so there are NO TOROIDS to wind.  Additionally a straight key is included on the pc board, just snap it off, mount it on the board, and the whole rig is then self contained.  Also included is an electronic keyer adapter - you can use your favorite keyer with the Cricket !

These are many features for such a low parts count and inexpensive transceiver.

ALL THROUGH HOLE parts make this kit very easy to assemble.  It will make a fine, fully functional, and educational first rig for a new builder, the new ham, or seasoned veterans wishing to just have fun with a new rig at minimal expense and effort.

This simple rig is fun and functional, and made many contacts at OzarkCon after the build session.  A proven design and a great choice for your next rig, it is perfect for a group build with nets and contacts after the build.  This is an excellent club project.
